Thanks for the replies. I am definitely going to invest in a tarp. I had been contemplating having a set up where I have one tarp that covers the tent then a second to be used as a communal area with the ability to join the two at the front if the site is small, however looking around it seems that the most common set up is a single tarp with the eating are along length of the tent. Does this have anything to do with the size of tent sites? Any suggestions/comments are appreciated.
